Dolphin Communication and Behavior

Scientist Rachel introduces a unit for grade four on Waves, Energy, and Information, focusing on dolphin communication in Blue Bay. Students will explore how dolphins communicate underwater using sound. The lesson includes listening to dolphin sounds and a story about Maria to understand sound transmission. Students are encouraged to hypothesize and investigate dolphin communication methods.
